a chemist designs a galvanic cell that uses these two half-reactions

A chemist designs a galvanic cell that uses these two half-reactions: half-reaction standard reduction potential Br2(D+ 2e-? 2 Br-(aq) red = + 1.065 V N29+4 H2)+4e -N2H4(a)+4OH (aq) Answer the following questions about this cell Write a balanced equation for the half-reaction that happens at the cathode 10 Write a balanced equation for the half-reaction that happens at the anode Write a balanced equation for the overall reaction that powers the cell. Be sure the reaction is spontaneous as written Do you have enough information to calculate the cell voltage under standard conditions? Yes No If you said it was possible to calculate the cell voltage, do so and enter your answerV here. Be sure your answer has the correct number of significant digits.
